Hi

With this query string, I get the error:


[19-Aug-2017 05:13:26 UTC] PHP Parse error: syntax error, unexpected '<' in /home/ecovibdc/public_html/ECOVIB2D/MYART/processmidpage.php on line 135
[19-Aug-2017 05:17:15 UTC] PHP Notice: Undefined index: username in /home/ecovibdc/public_html/ECOVIB2D/MYART/ecovib2d1.php on line 187
[19-Aug-2017 05:17:15 UTC] PHP Notice: Undefined index: email in /home/ecovibdc/public_html/ECOVIB2D/MYART/ecovib2d1.php on line 187

When I load ecovib2d1.php, load the graphic and hover over the buy button, I get a 'NaNNaN.........' type of output on the status bar.


I do not know what is happening?

I think I have defined username and email correctly in the query string?



document.getElementById('form').action="http://103.226.223.161/~ecovibdc/ECOVIB2D/MYART/processmidpage.php?username=" + <?php echo $_GET['username'];?> + "&email=" + <?php echo $_GET['email'];?> + "&Person=" + personname + "&Price=" + Priceofart + "&Graphic=" + picname.replace('w.bmp','.bmp');


Thanks.

I don't use $_GET very often. I didn't know $_GET would unencode query string values.

You seem to have missed the point of my suggestion. Seems you did remove line 187 but you replaced it with this:
CODE
            function dec(){
            var url = 'http://103.226.223.161/~ecovibdc/ECOVIB2D/MYART/processmidpage.php?Person=personname&Price=priceofart&Graphic=picname&username=';
            var url1 = <?php  echo $_GET['username'] ?>;
            alert(url1);
            var url2 = '&email=' + <?php echo $_GET['email'] ?>;
            document.getElementById('form').action = url + url1.replace('+','%20') + url2;
Using PHP here is wrong. PHP is only active when the page is loading. When the page loads there is no query string values for 'username' and 'email'. And, you can't use $_GET to retrieve values that haven't been entered yet. Forget about building the query string yourself. PHP will do that for you when the form is submitted.

This is your current form:
CODE
            <form  id='form' action='processmidpage.php'  onsubmit='dec();'  method="GET"/>
            <input type='hidden' id='person' name='Person'/>
            <input type='hidden' id='Cost' name='Price' />
            <input type='hidden' id='pic' name='Graphic'/>
              
                        <p align='center' id='freename'>Enter Full Name:</p>

            <p align='center'><input id='Nameofperson' maxlength='50' name='username' size='50' type='text' /></p>

            <p align='center' id='freeaddress'>Enter Email-Address:</p>

            <p align='center'><input id='e-address' maxlength='50' name='email' size='50' type='text' /></p>
            <input type='submit' id="Buy" value='Buy Now'/>
            
            </form>
Any Javascript that affects 'Person', 'Price' or 'Graphic' values will have to be changed to use these inputs. Remove the function dec(), you don't need it. Be sure to remove the 'onsubmit' event from the form. After you make these changes and load the page again, all you need to do is fill in the username and email then click the submit button.

When 'processmidpage.php' loads it will have a query string like this:
CODE
http://103.226.223.161/~ecovibdc/ECOVIB2D/MYART/processmidpage.php?Person=value&Price=value&Graphic=value&username=value&email=value
PHP will build the query string for you, based on the fields in between the <form>...</form> tags.
